GAS-BURNER.

Specification of Letters Patent.

Application filed March 31, 1910.

Patented Aug. 30, 1910. Serial No. 552,571.

To all 'whom it may conccrn:

Be it known that I, VALTER ROBERT VVUL- neon, a citizen of the UnitedStates, residing at- Cincinnati, in the county of Hamilton and State ofOhio, have invented new and useful Improvements in Gas-Burners, of whichthe following is a specification.

This invention relates to improvements in gas burners such as areemployed with cooking stovcs, hot air furnaces, steam and hot waterboilers and has for its object the 'pi'ovision of a burner consuming amixt-ure illustrated in the acoompanying drawings and more particularlypointed out in the appended claims; it being understood that variouschanges in the form, proport-ion, size, and minor details of the devicemay be made, within the scope of the appended claims, without departingfrom the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, forming a part of thespecification;-Figure l is a side elevation of the device. Fig. 2 is aplan view of the same. F ig. 3 is a Vertical section taken on the line 3-3 of Fig. 2.

Similar numerals of reference are employed to designate correspondingparts throughout.

The body of the burner is designated by the numeral 5 and while I haveshown the same to be annular in contour it must be understood that I amnot to be limited to this specific Shape, since it will be readilyunderstood, from what will appear later, how the body could be oblong orin fact formed to any shape without departing from the spirit orsacrificing any of the advantages of the invention.

The body 5 is preferably formed of a single piece of metal and may becast or otherwise formed to the shape specified. As shown in thedrawings the burner is a tubular structure formed into an annulus and onits outer side and at the junct-ure of its upper and lower outersegments is split, such split extending entirely around the burner,whereby a combustion opening 6 is provided the opposite sides of whichare designated by the numerals 7 and 8. The upper side '7 is extendedbeyond the side 8 and directed downwardly and over the side 8, as shownin F ig. 3 with its inner surface spaced from the adjacent surface ofthe side S. Writh this construction it will be manifest that theoverlapping side 7 will act as a defiect-or for the flame in the opening6, whereby the fiame nearest the opening will be directed downwardly andonto the parts to be heated.

The pipe which supplies the mixture of air and gas to the burner isdesignated by the numeral 9, having one end fiared to receive the gassupply pipe 10, the said fiared end and pipe 9 being greater than thediameter of the gas supply pipe so that the gas passing through thelatter will be mixed with the air passing through the fiared end of thepipe 9. The pipe 9 terminates at the medial portion of a horizontaltubular extension 11, the opposite ends of which are tapped into thebody of the burner at diametrically opposite points, as clearly shown inFig. 3.

Vith this construction it will be manifest that a mixture of air and gaspassing through the tubular extension 11 will enter the burner atopposite point-s and exit through the combustion opening 6 atI which itmay be ignited and owing to the continuous opening 6 a solid wall offlame directed in a downward extension will be produced.

From the foregoing, it is evident that I have provided a device which iscomparatively simple in structure, and inexpensive in manufacture,embodying few parts and these so arranged that the danger of derangementwill be reduced to a minimum.
